How to reset the tire pressure light on a Mercedes-Benz C260?

First, ensure the key is turned to the second position. Use the left-hand menu button on the steering wheel to display the odometer interface on the dashboard. Then, press the up button on the left side of the steering wheel, followed by the (R) button on the dashboard. The dashboard will display 'Is the tire pressure normal?' Next, press the + button on the right side of the steering wheel and wait for 10 seconds before turning off the key. After restarting the vehicle, the tire pressure warning light should disappear.

I recently dealt with this issue, and resetting the tire pressure light on a Mercedes C260 requires specific steps. First, ensure all tires are inflated to the standard values, referring to the cold tire pressure label on the door frame. Then, start the ignition without moving the car. Navigate to the 'Vehicle' menu on the center display, open the 'Tire Pressure' option, and select 'Restart TPMS.' After confirming, the system will begin recalibration. Remember to drive at a steady speed for about 15 minutes to allow the sensors to relearn the tire data. If it doesn't succeed the first time, there might be a slow leak—check the tire walls and wheel rim edges with soapy water. For a more thorough solution, have a technician refresh the system during maintenance, as German cars' electronic systems are quite sensitive.

Last time my tire pressure warning light came on, it was a headache, but fixing it myself was quite simple. First, measure the pressure of all four tires when the car is cold, and use an air pump to inflate them to the values indicated on the door frame label. Then, get in the car, turn on the ignition without pressing the brake to start the engine, and use the touchpad on the left side of the steering wheel with your right hand to navigate to the 'Service' menu. Find the tire pressure monitoring option and select 'Reset.' When the system asks 'Is the tire pressure normal?', click 'Yes.' The key is to immediately drive on a highway at a steady speed for about 10 kilometers, as bumpy roads can interfere with the calibration. I noticed the system is very sensitive to tire temperature—on hot days, you can't adjust it right after driving; you have to wait until the tires cool down completely. If the light still flashes after resetting, you might need to consider an issue with the wheel speed sensor, which can't be fixed on your own.

As a car modification enthusiast, I've studied Mercedes' tire pressure logic. The key to resetting the tire pressure light is to have the ABS wheel speed sensors relearn the data. To operate, go to 'Settings'-'Vehicle Data'-'Tires' in the central control screen, manually reboot the system, then drive to synchronize the rotation counts of all wheels. Pay attention to the spare tire pressure as the system monitors it too. If you've changed wheel sizes, the factory calibration may fail easily – it's recommended to visit a dealership for diagnostic computer matching. In northern winters, tire pressure fluctuates significantly; checking monthly can prevent false alarms. Once my tire pressure was normal but the light stayed on due to poor sensor contact caused by a deformed wheel rim.

A friend's newly purchased C260 encountered a tire pressure warning light, and I summarized some tips while helping him resolve it. To adjust tire pressure, refer to the standard value chart inside the fuel tank cap—the numbers vary based on different load requirements. Resetting the system only takes four steps: after powering on, locate the tire option in the maintenance menu on the central display, confirm to restart the system; start the engine; hold the OK button on the steering wheel for 3 seconds; drive two kilometers, and the light will turn off naturally. Avoid performing this on a slope, as body tilt can affect calibration accuracy. In cold weather, tire pressure drops faster—wait half an hour after inflating before resetting for better accuracy. Mercedes' indirect tire monitoring system eliminates the need for sensors, but a reset is mandatory after tire repairs.

My old C260's tire pressure light comes on several times a year, and I've figured out a cost-effective solution. Buying a mechanical tire pressure gauge is more reliable than electronic ones. Inflate to 2.2 bar for front tires and 2.5 bar for rear tires as reference. No professional tools needed for reset: After starting the car, simply press the HOME button on the center console, go to 'Vehicle Settings', select 'Tire Pressure Loss Display', and click 'Now' for immediate effect. I've also tried activating it with a diagnostic tool via the OBD port, but the system automatically calibrates after 15 minutes of driving under normal conditions, which is more convenient. If false alarms are frequent, it might be due to dust on the wheel speed sensor—cleaning the connector after removing the wheel can help. Tire pressure fluctuates more during rainy seasons, so adding a tire pressure cap for constant monitoring is recommended.
